Configuring the Bridge

3.5.2Destination Indexes 0 and 254: Dynamic Message Routing

The bridge provides a means for dynamic routing of messages at runtime. Dynamic routing applies only to messages initiated from TCP/IP hosts, and requires the host to configure the bridge at runtime (to Destination Index 255).

You should be aware of your options for using dynamic routing in your application, as you setup your mapped routings. Two Destination Indexes are reserved for routing messages dynamically: 0 and 254 decimal. Your options are:

H Destination Index 0: Host-based routing A Modbus Plus routing path is available in the bridge at index location 0 for runtime use by TCP/IP hosts. When the host configures a path in the bridge, any message from that host addressed to index 0 will be routed to that Modbus Plus path. The bridge maintains a cache of up to 10 associations between TCP/IP hosts and Modbus Plus paths.

This routing option allows the bridge to be configured for simple addressing to Modbus Plus from TCP/IP nodes which do not support gateway routing.

H Destination Index 254: Socket-based routing A Modbus Plus routing path is available in the bridge at index location 254 for the current TCP/IP host connection only. The bridge maintains one socket connection at that index location for each of its eight Program and eight Data paths.

This routing option allows the bridge to handle concurrent sessions from one TCP/IP host, or from multiple hosts, using independent routing assignments. It provides flexibility for your application to manage routing dynamically, in addition to the bridge’s fixed mapping table.

Section 3.9 provides examples of dynamic routing.

3.5.3Destination Index 255: Bridge Internal Command

Messages received by the bridge addressed to Destination Index 255 cause the bridge to execute an internal operation. This index is used to configure the bridge for dynamic routing, or to invoke an upload or download operation between the host and bridge.

Section 3.9 provides examples of dynamic routing. Sections 5.2 and 5.3 provide examples of uploading and downloading.

3.5.4Reserved Destination Indexes

Destination Indexes 250 ... 253 are reserved and are not available for use.
